The K20D72M Tower MCU Module (TWR-K20D72M ) is a low-cost evaluation, demonstration and development board, which features the Kinetis K20 72MHz low-power microcontroller. These devices are based on the ARM® Cortex™-M4 architecture with USB 2.0 full-speed OTG controller. The TWR-K20D72M microcontroller module can operate in stand-alone mode or as part of the Freescale Tower System, a modular development platform that enables rapid prototyping and tool re-use through reconfigurable hardware.

The K20 MCU family is pin-, peripheral- and software-compatible with the K10 MCU family and adds Full- and High-speed USB 2.0 On-The-Go with device charger detect capability. Devices start from 32 KB of flash in 5x5 mm 32 QFN packages extending up to 1 MB in a 144 MAPBGA package with a rich suite of analog, communication, timing and control peripherals. High memory density K20 family devices include a single precision floating point unit and NAND flash controller.
